Answer:

An ecosystem is a community of living things and their non-living environment, and may be as large as a desert or as small as a puddle. An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter. All ecosystems require energy from an external source – this is usually the sun.

The power delivered by the motor lift in elevating the 10 passengers at the speed of 16.8 m/s is 205800 Watts

<h3>What is power? </h3>

Power is simply defined as the rate at which energy is consumed. It can be expressed mathematically as

Power (P) = Force (F) × velocity (v)

P = Fv

<h3>How to determine the force </h3>
  • Mass (m) = 1250 Kg
  • Acceleration due to gravity (g) = 9.8 m/s²
  • Force (F) =?

F = ma

F = 1250 × 9.8

F = 12250 N

<h3>How to determine the power </h3>
  • Velocity (v) = 16.8 m/s
  • Force (F) = 12250 N
  • Power (P) =?

P = Fv

P = 12250 × 16.8

P = 205800 Watts

Study the image.
NNADVOKAT [17]
C. the left plate is positively charged
when looking at these arrows imagine there is a positive electron at the beginning of the arrow. Since the electrons are going towards the plate to the right it is attracted to the negatively charged plate. These electrons want to get away from the positively charged plate because same charges repulse each other
